TYPE MOLD AND MATRIX.

Patented Feb. 26, 1907.;

To all whom it may concern:

Be it known that we, FRANK H. BROWN i and JOHN E. HANRAHAN, of the cityof Baltimore and State oi Maryland, and GEORGE A. BOYDEN, of MountWashington, in the county of Baltimore, State of Maryland, citizens ofthe United States, have invented certain new and useful Improvements inType Molds and Matrices, of which the following is a specification.

. This invention relates to type-molds, and has among its objects toprovide a mold by which type of a wide range of sizes and styles may becast and by which the changes from one size type to another may be madequickly and the centering of the type character on the matrix withrespect to the mold-cavity be made accurately without measurement and byunskilled labor.

Theinvention is illustratedin the accompanying drawings, in which,

Figure 1 shows a perspective view of the mold parts. Figs.2, 3, and 4show sectional views of insert-molds and portions of ejectors of varioussizes. Fi s. 5, 6, 7, 8, 9, and 10 show matrix-plates a l of a uniformor equal ters they contain. Figs. 11 and 12 show space or quad matrixplates. Figs. 13, 14, 15, 16, 17, and 18 show ty e of varying sizes castfrom matrices the p ates of which are of uniform size, all cast i'romthe same stationary mold part. Figs. 19 and 20 show spaces and quads ofdifferent sizes. Fig. 21 s owe a longitudinal section through theinsert-mold part with the matrix-holder and matrix held in place by theadjusting or centering screw, and Fig. 22 shows aperspective view of thematrix-holder with the centering recess in the rear side thereof.

Heretofore it has been the practice in making tjr e, s aces, and 'quadsto have separate mo d mec anism for each bod wise size of type and touse matrices forme in lates varying widely in dimensions to accor withthe size of the type to be made. This old ethod requires .a change ofall the mold rts and numerous adjustment of same each time a change ismade from one size or kind of type to another and also requires numerousadjustments of the matrices with respect to the mold to get the typecharacter on the matrix properly situated or centered,

the whole requiring skilled labor of exceptional ability. Thedilliculties inherent in this method have resulted in confining themaninacture of type to i'oundries provided with special equipment andskilled labor, and the type thus produced has been sold from theIoundries and distributed to printers throughout the country.

The present invention contributes in an important manner to theovercoming of many of the diiiiculties herein mentioned and enables themethod or practice alluded to to be dispensed with. j

The mold in this instance consists of four parts-a stationary mold part1, which in practice is permanently attached to the castmg mechanism andis used to cast all kinds' and sizes of type within the size range ofthe machine; an insert-mold part 2, an ejector 3, and a matrix.

The plate or body part of the matrices will be of a uniform sizeirrespective. of the size or kind of t pe character; but the insert-moldparts and the ejectors will vary in size as to their bodywise ca acity,and the difl'erent sizes will be interc angeable with respect to thestationary mold part. The arrangement, construction, and o eration ofall these parts is such that their a justment for ty e of differentsizes will not require special sizill.

The stationa mold art consists of a baseblock 4, which orms t e bottomwall of the type-cavity and is provided with a nippleplate 5, through ahole in which not shown) the metal is su plied to the mold-cavity incasting. An aiiutment 6 is attached rigidly to the base-block 4, andagainst this abutment a shoulder on the ejector 3 strikes when it is inthe casting position. A series of thin plates 7 of dilierentthicknesses, which we term liners, are employed. Any selected number ofthese liners maybe placed against the abutment 6 to govern the positionoi the cjecior, and thereby regulate the sctwise size of the type-cavityto correspond with the type characters.

On top of the base-block is the ejector 3, which forms one side wall ofthe type-cavity. This ejector has a reciprocating movement on thebase-block 4, by which the type is ejected from the mold parts ai'terbeingcast. In one side of the ejector is a recess 8, which permits thereciprocation of the ejector past the abutment 6. A shoulder at one endof the said rece strikes against the abutment 6 (or against the liners 7when the latter are inserted) when the ejector is in the castingposition, as before stated.

The insert-mold part 2 consists of a rightangle piece which forms two ofthe walls of the mold-cavitythat is, the top -and one side-when placedin position with respect to the stationary mold and ejector. Theinsertmold part is provided with a recess 11 and a matrix-holder whichreceives and properly locates any one of the matrices irrespective ofthe size or kind of type to be cast, and this matrix-holder consists ofa backing-plate 9, provided with )rojecting flanges 10, so arranged thateac matrix of the font or any matrix of any font can be readily placedin said holder between said flanges in proper position for castingpurposes without measuring or requiring skill. This matrix-holdercontaining the desired matrixds then placed in a recess 11 in theinsert-mold part especially designed to receive it, and by means of acentering-screw 12, having a cone-shaped end 13, which enters asimilarly-shaped recess 14 in the matrix-holder, said holder containingthe matrix may be accurately centered by merely turnin the screw, whichalso holds and keeps the proper position in the insert-mold art.

All matrix-plates to be used wit the mold mechanism are to be of auniform size irrespective of the size or kind of type characters, spacesquada or, ornament to be cast from t em, and the type character in eachand all of the matrix-plates has the same predetermined position withrespect to one vertical ed e and the bottom edge of the plate and is soocated that every matrix of a font or of a series 01 fonts isinterchangeable with the mold mechanism. In changing from one setwisesize tvpe character to another all that is required to center thecharacter on the matrix with respect to the mold-cavity is to place thematrix in the matrix-holder 9 and secure the holder and matrix in theinsertmold part 2 by turning the screw 12. The

- matrix-holder will thereby be shifted to ac curately center the matrixcharacter with respect-to the mold-cavity, and the whole is ready forcasting the type selected without having required skilled labor.

It will also be seen that no matter what the size of the character onthe matrix-plate may be the turning of the screw Wlll cause thecharacter to take its correct position, and the adjustment is the samein every case.

It will also be seen that as the matrixplates are all of a uniform sizeand the characters thereon have the same position 'with respect to twoedges of the matrix-plate when a matrix is placed in the holder thecharacter irrespective of its size will have the same definite positionwith respect to the reolder And matrix in cess in the back of theholder, and therefore the centering of the matrix can be readilyaccomplished by the adjusting-screw entering said recess.

Having thus described ourinvention, what we claim as new, and desire tosecure by Let-. ters Patent, is- 1 1. In a machine for casting type, thecombination of a type-mold having a movable ejector forming one side ofthe mold cavity; a matrix-plate having a casting-surface whose area isof size sufficient to receive any type'character from the smallest tothe largest dimensions. for which the machine has capacity-saidcharacter, irrespective of its size, being situated on the said plate ata pr'edetermined measurement from one vertical edge and the bottom edgeof said plate;-and

insertible and removable liners which by limiting the movement of theejector governs. the setwise size of the mold-cavity.-

2. In a machine for casting type, the combination of a type-moldcomprising a-stationary part and an insertible part; a matrix platecarried by the said insertible'part and iaving a casting-surfacewhose-area is of size sufficient to receive any type character-from thesmallest to the largest dimensions for which the'machine hascapacity-said'Chttfiacter, irrespective of its size, being situated onthe said plate at a predetermined meals" urement from one vertical edgeand the bottom edge of said plate; and means also on'th'e insertiblepart of the mold to shift the-'matrix-plate so as to center thematrix'chara'c ter with respect to the mold-cavity.

movable holder for the matrix-plate; and
